I did enjoy it, it is the first drawing I've ever seen from you. Specially the sense of movement it has. The minimalistic background helped with the drama it needed to have.

But the way you drew and shaded the left arm, the hand and the violin made the perspective look rather flat on that region of the piece. As it is an awkward position arm-wise, you could have avoided the complex sleeve, or kept the sleeve and find another point of view for the arm.

I checked your body of work and it is not something constant, but I find it present in this one.

I really like this. The position of the hands are very accurate, except for one thing. I would probably make sure the thumb is somewhere visible, on the bottom of the bow between the index and middle finger preferably. (not sure if that's clear enough xD)

Like I said before I really like this, and you did a great job with it! c:
